During the history of curtain wall development, its direction has been always led by the design concept and technical level from European and American countries.

After years of engineering applications experience, summarized a systematic set of curtain wall industry standard, and established curtain wall window opening mode, named top-hung outward open.

Meanwhile, the hardware for window opening also has been standardized, from single point to high performance multi point locking.

HOPO, besides continue above standardized solutions, at the same time, goes on with deepening hardware configuration, and adopts single direction & double direction transmission for multi-point locking. In particular, double direction transmission has much better capacity of wind pressure.

For the control function, installed handle developed into separable  handle, which can control the users, to facilitate unified management. For appearance, adopts new designed concealed gear box, which makes no hardware outside, improving the overall aesthetics of the curtain wall.

With its graceful arc, HOPO curtain wall hardware products interpret the refinement and sentiment; the sculpturesque texture reveals the distinguished quality. Visual decides tastes while technology creates the brand. Open the window, enjoying the constant aesthetics by visual.
